Background: The global incidence of colorectal cancer (CRC) is expected to be increased by 60% until a few years. Despite the advances in surgical and chemotherapy techniques, a significant proportion of patients with CRC have poor responses to treatments. These are the reasons that prove the importance of identifying molecular bio-markers as potential therapeutic targets. Long non-coding RNAs (lnc RNAs) participate in the initiation, development, progression, and metastasis of cancers such as CRC. Hence, this class of noncoding RNAs is known as bio-marker for cancer dia-gnosis and prognosis.
Materials And Methods: In this experimental study, the extraction of total RNA from tissues, synthesis of complementary DNA as well as quantitative real-time polymerase chain reaction (qRT- PCR) were performed. Comparative cycle threshold method was applied to quantify the expression level of lncRNA-SNHG7 and FAIM2. The relative amount of lncRNA-SNHG7 and FAIM2 was calculated using the equation 2 -DDCT.
Results: In this study, by qRT PCR, we concluded that the expression level of SNHG7, as a recently identified lncRNA and FAIM2 were increased in colorectal cancer tissues compared with normal adjacent tissues.
Conclusion: Our study indicates the potential importance of SNHG7 and FAIM2 expression for more studies in future.

Objectives: Long non-coding RNAs have identified to involve into the tumour cell proliferation, apoptosis and metastasis. We previously found that up-regulated LncRNA-SNHG7 (SNHG7) positively correlated to the Fas apoptosis inhibitory molecule 2 (FAIM2) in lung cancer cells with unclear mechanism.
Methods: Non-small cell lung cancer (NSCLC) and relative normal tissues (n = 25) were collected.
lncRNA-SNHG7 promotes the proliferation, migration and invasion and inhibits apoptosis of lung cancer cells by enhancing the FAIM2 expression.

There is growing evidence that long non-coding RNAs (lncRNAs) are related to cancer development. In the present study, we found that the expression levels of lncRNA-SNHG7 mRNA and protein obviously increased in lung cancer tissues compared to adjacent non-cancerous tissues. Simultaneously, the expression levels of Fas apoptotic inhibitory molecule 2 (FAIM2) also increased in lung cancer tissues.
